yIMPROVEMENT IN HOT-AIR REGISTEFOS.

Specification forming part of Letters Patent No. 136,682, dated March 11, 1,873.

pipes so that the falling of the sweepings and other matters into the pipes is eifectuallyprevented, the whole being inclosed in au ornamental guard or screen of open metal-work, which protects the pipes and hides them and the opening through the floor from view.

Figure l isa sectional elevation of my improved register taken on the line w x of Fig. 2, and Fig. 2 is a horizontal section taken on the 1ine`y y of 1.

Similar letters of reference indicate corresponding parts.

A is the hot-air pipe, which is extended considerably above the door B, as shown, a large hole, O, being made for it through the floor to allow a sufficient circulation of air to prevent the ignition of the wood and save the expensive illingin ofsoap-st'one, marble, or other nonconducting substances commonly used around the pipes when stopping at the door, not only as a protection against fire, but toprevent the falling of small objects through that may happen to lie on and be moved about the floor. D represents the valve in the top of the pipe, and E represents the screen'and guard.

Byhaving the pipes thus extended and guarded the necessity for a filling around the pipes as a preventive to the fall of objects through is avoided, and a considerableexpense is thereby saved, for such illing must of necessity be of non-conductn g material, whichis expensive, and by having the pipes thus extended the collection of refuse matters in passing through and a considerable distance above the floor, as and for the purpose described.

2. The screenguard E, arranged with respect to a hotair pipe, A, as and for the purpose set forth.
